Advanced telemetry systems for research, development and production

For measurements on rotating components and moving machinery, imc offers modern telemetry systems for a wide variety of tasks: whether single-channel torque monitoring of a rotating shaft, multi-channel strain gauge and temperature measurements on a train wheel-set or non-contact power measurement on a vehicle drivetrain in harsh environments. There are transmission electronics available for a large variety of sensors, such as strain gauge (quarter-, half- and full-bridge), thermocouples, PT100/1000, as well as IEPE sensors and voltage signals.

In Practice

Automotive

For applications in the automotive industry, imc offers robust and compact wireless telemetry systems for the non-contact transmission of measurement data for torsion, temperatures, forces and vibrations of rotating parts on vehicles.

Aerospace

For use on helicopters and aircraft, imc offers robust radio telemetry systems with up to 64 channels. The systems are specially designed for mounting on rotating parts, e.g., rotors, propellers, wheels or other rotating machinery. All measurements are simultaneous and the signals are digitally transmitted wirelessly. All transmitter electronics are protected from water according to IP65 and the sensors, e.g., strain gauges, thermocouples, PT100/1000 or IEPE are connected via waterproof connectors.

Rail

Railway applications require particularly robust telemetry solutions, such as when testing axles, drive, motor and gear shafts or other rotating powertrain components. Up to 256 sensor signals, e.g., strain gauges, thermocouples or vibration sensors can be detected and transmitted simultaneously. The space-saving, non-contact transmission technology simplifies the implementation of the measurement system and ensures the most accurate measurement results.

Marine

Our telemetry systems for torque measurements on marine vessels and engines are easy to install and are available in various sizes – matching the drive shaft. Depending on the particular measurement task, single or multi-channel systems can be used. Many powertrain components of ships, such as gear shafts, have been successfully tested with imc telemetry solutions to optimize their performance, efficiency and cost-effectiveness.

Mechanical Engineering

Whether on motors and generators, machine tools, rolling mill drives, paper machines, marine drives or wind turbines: these telemetry systems allow for non-contact transmission of measurement variables, such as torque, force, pressure, vibration and temperature. Measurement systems with up to 256 channels and data rates of up to 10 Mbit/s are available.

Wind Energy

For applications on wind energy systems, imc offers flexible telemetry solutions that support users in a wide variety of tasks: whether to measure torsion and bending moments on a wind turbine‘s main or generator shaft or to determine side load, rotor position and blade angle on a rotor blade.

Commercial Vehicles

The demands on modern heavy-equipment such as excavators, wheel loaders, forklifts and agricultural machinery are high. In addition to robustness, efficiency plays an increasingly important role. When optimizing drive systems, telemetry solutions can help. Measurements such as torque, efficiency, temperature, pressure, traction and bending can be acquired without contact by the telemetry systems.

Test Stands

The telemetry systems are ideally suited for continuous use in test mode. They detect non-contact torques and vibrations on drivetrains, transmit the temperature of brakes, tires and wheels, and record forces on gearbox and clutch test stands. The high data rate of up to 10 Mbit/s ensures reliable transmission, even with dynamic sensor signals.

Complete solution

For holistic testing on vehicles, wind turbines and machinery it is often necessary to acquire additional measurement variables in addition to the telemetry data. The telemetry solutions allow for a direct connection to imc measurement systems. These instruments provide measurement modules as well as interfaces to typical process and fieldbus systems for all common signals and sensors. The imc system collects and synchronizes these multi-domain data and allows for further processing and analyzing in real time.Results can then be passed on to overarching systems such as controllers or cloud data bases via multiple networking options.
